i agree, but even such a move to more open business systems would not obviate the need for an enterprise web cms. not sure how much integration requirements with variety of proprietary systems forms part of the enterprise cms price premium. might be in the consultancy costs where that really starts to mount up.
yes, but historically the same systems were run much more cheaply on council run cobal/fortran. The last govt offered huge grants to councils to move them from these ageing systems because the cost of maintaining and integrating them was so high - the argument given was that it would lower costs. Now companies such as capita are profiteering this move. 'openness' - at the least I would expect a cost and license free API that uses open standards to allow competitors to integrate with the product - built into the original contract.
